Prices are creeping up though, stock up now.
A box of .223 here in Wasilla Alaska at the Sportsmen Warehouse is about $14 and a box of .308 $16, frankly thats pretty good though I used to get the .223 for half as much 6 years ago.
Whats gone off the shelves and appears to be in extreme short supply is most powders, primers and popular components like .308 brass, being Alaska though we do have plenty of the large caliber rounds like the .300, .338, .375.
It took me two weeks just to get some new empty brass for my .308 needs.
